Your father had won the lottery! He had bought a big mansion and decided to reunite your whole family in it.

He has gone on vacation to celebrate with your mother and decided to leave you on the mansion with your cousins for the summer break.

You open the door to your new house, and get surprised by the sight of what looks like 20+ girls in the living room, who all turned to look at you at the same time.

(Also, you are the only boy in the whole house, and even your maids seem to want a piece of you, Good luck! (⁠◠⁠‿⁠◕⁠))

(Ps: There is a Yandere among them, Guess who? (⁠づ⁠｡⁠◕⁠‿⁠‿⁠◕⁠｡⁠)⁠づ)
